'oABLEcAnnIER SYSTEMQ To all whom it may concern.

Be its-known that I, FRED citizen of the United States, residing atLowell, in. the county of MiddleseX and State of. Massachusetts, haveiinvented certain new and useful.Improvements in Gable- Carrier Systems,ofv which the following is a specification. 1

This invention relates to. apparatus, disposed at stations of a cablecarrier system, for despatching and'receiving carriers, and

. is particularly adapted to what are known as high-line drop stationsin systems of .this character. Features thereof may also be employed toadvantage in low lin'e systems, and. indeed in systems other than thoseusing a.

cable for the transmission of carriers.

One of the objects of the present invention is toprovide an improvedmeans for elevating a carrier from a station or point disposed at arelatively low level, to a track at a higher level and then toautomatically connect the carrier to a propelling cable or otherwiseSubject it to a propulsive efiort, in such manner as to avoid collisionswith other carriers en route past the station.

Anotherobject of my invention is to provide a carrier-hoisting mechanismwhich is set into. operation by a downward push upon the carrier itself,after the latter has been inserted .in said mechanism. I-have furtheraimed to provide an improved means whereby this hoisting ,mechanism maybe intermittentlyoperated, as needed, by; power derived from the cableor like means which propels the carriers along the main track.

- Still another object of the invention is to provide an improved meansfor operatively:

engaging and disengaging-carriers with, the propelling means. r

These and'other ob ects of my lnvention will be hereinafter referred toand the novelelements and combinationof elements whereby they may beattained will be particul'arly pointed a 1 anaybeamade herein withoutdeparting from Specification of Letters Patent.

out in-the claims appended hereto.

In. the drawings I have exemplified certain pr'eferredforms of theapparatus-in question, but I am aware that various otherchanges andmodifications than those shown.-- p w designated 2 (and which may hencefor specification.

' Referring to the drawings: Figure 1 is a front elevation of ahigh-line drop station. Fig. 2 is a section of the apparatus shown inFig. 1, taken on line II-I1 of said figure; the station proper beingshown in Fig. 3 is a detail section taken on line III-{II of F ig. 1.Fig. 4: is a fragmentary rear elevation of the mechanism for trippingfree the carrier cable-- gripping device and for thereafter causing saiddevice to reengage the cable. Fig, 5 is a front elevation of a modifiedform of high.

line-drop station; the carriers onthe-main track having in this type ofapparatus the right of way over carriers being delivered t said maintrack from the station. "Fig. 6 is a front elevation of still anotherform of the apparatus in question; the carriers from the station havingthe right of way over carriers traversing the main track in this form ofdevice, as in the device shown in Fig.1, Fig. 7 is a section taken online VIIVII of Fig. 6, and Fig. 8 is a horizontal detail section takenon line VIII VIII of Fig. 6.

The several modifications will be sep arately discussed.

Considering. first the plane in a known manner. The lower, or

outgoing track in the apparatus exemplified has the rails 22 thereofdisposed inlthe same vertical plane, but I do not wish, to be limited inany way to such disposition of. the'rails Where the claims do. notclearly specify such arrangement.

The main tracks have been respectively designated forwarding and returntracks, with respect to the drop or clerks station and not. with respectto the jcashierls. station. A track comprising ralls 3 3 extends upvertically from a point convenient to the,

operative and is adapted to deliver, carriers to the'track the rails. ofwhich have been brevity conveniently be referred to as track 2) when aswitch t is in its elevated position,

j indicated by dot and dash lines at 4 in Fig;

1. Acable 5 serves to propel carriers in the direction indicated by thearrows adjacent thereto, along the respective main tracks; and thiscable it'will be'inoted is normally substantially free from kinks orbends where passing a station of the character in question; a feature ofconsiderable importance.

An independent drop track 6-6 is adapted" to receive carriers from aswitch 7 to which selective carriers are delivered in aknown manner fromthe upper'or horizontal track 1. The respective trackseotions and switch7 I aresuitably connected together and supvported by brackets orconnections 8, 9, 10,

11, 12,13, 14, 15'and 16, the switch 4: being mounted upon a shaft 17journaled inthe' bracket 9 and most of the remainingbrackets servingfurther to support operat- *scription adapted to co-act with the rails,-but it is preferably of substantially the form ing cams, .or the like,in the manner hereinafter described. 7

'The shaft 17 has mounted thereon adja-' cent its rear'extremity an arm18 which has -journaled in its free end a spindle 19 upon the rearextremity of which is keyed a spool 20 and' upon the inner end of whichis asmall pulley 21. This pulley is preferably provided with aroughenedsurface at the periphery 22 thereof to' better adapt it for"driving engagement with the cable 5.

,Journaled in the lower portion'of the bracket 10 is an idler 23 uponwhich normally the cable 5 lightly rests, but which, when thearm 18 isrotated into its position indicated by dash and dot lines 18, kinks orbendsthe cable into driving engagement with the pulley 21. At such timeobviously the spool 20 will be roated in the direction of the arrowadjacent thereto andsaid'spool will thereby wind up upon itself ahoisting cord 24. This cord has its lower extremity attached to apusher25,;which, as indicated in Figs. 1 and 2, ridesjbetween the rails33. This'pusher may be made of fiber or other suitable material andcarries ahook 26, the:

function of which will be hereinafter referred to; The respective rails3 are bent out treat 27 to provide an openingthrough whichthe guide orretaining lugs28 of the carrier 28 may be inserted into operative;

engagement with the pusher 25 as shown in Fig. 1.

The carrier 28 may be of any suitable deshown in Fig, 4; the bottom ofthe carrier 2 e carryinga'cable-gi'ipping lug 29 and beingos'l'ottedas'at30, in a known manner, to per- "mitthe'pro ectionthr'ough said slot of a piv-floted cable gripping member 31. 7

member 81 of the carrier is in'its closed 'position, acami35 in thepath, of the ascending 7 carrier will force this member into its openposition preparatory. for v its engagement with the cable5.' Y

.Thebridge e is slotted at its freeend, asat 36 (see F igsfil-and forthe'reception 311-1 ternately of the reduced sections 37 8 7"of thelonger rail 3 and upper rail '2, so that whether the bridge is down orup, it is rigidly held against lateral movement. The rear side of saidbridge, as viewed in Fig. 1,

; The means for preventing collisions be-' tween carriers en route,along main track 2 and carriers being despatched from the clerks'station will now be described.

Pivotally connected at 45 to the arm18 is a bent link 46, the right handend of which, as viewedin Fig. 1', is'connected at 47 to an L-shapedmember 48. The latter .is pivoted at 49 to the bracket 12 and thedistance between the pivotal axes 47 and149 is substantially equal tothe distance be-' tween the pivotal axes 45 and 17.; so that thestraight half of link 46', adjacent member 48, is always held paralleltothe cable or track 2. Intermediate members 48 and 18 is a second 'Lshaped part 50 which is pivotally connected to the link 46 at 51' andalso pivoted at 52 to bracket 11. The distance between axes 51 and 52 isagain made equal it may to that between axes 47 and 49, and obviouslymembers 48 and 50 rotate together, clockwise Lor counter-clockwise asthe case may be.

T hefree end53 of the. member 48 is bent o er as shown to adapt it forengagement with the pivoted element 31 of the carrier grip, so that whena carrier'travelingover track 2 approaches a station from which acarrier is being despatched and thebridge of which station has beenraised, its pivoted jaw or grip 31 strikes said end 53 and such carrieris released from the cable to continue on by momentum alone until itstrikes the free end 54 ofthe member 50 which at'su'chtime is disposedin its dotted line position.

This element positively stops the carrier. It

will be observed, too, that the element 54 is also adapted toopen thegrip 'ofthe carrier as well as to stop the latter should the memgagedfrom said rails.

-when the bridge is open, lies immediately below the'grip elements ofthe arrested car'-' rier on track 2, so that as it rises its: uppervedge 46, indicated by. dotted lines in Fig. 4, engages the pivoted jaw81, shown by dotted lines in its lower position in said figure, andpresses it upwardly a sufiicient distance to enable the jaw to besnappedclosed by its spring in the interior of. the carrierbottom: although themovement of the cable alone when the pivoted :jaw is brought intocontact therewith will normally pull this part around the remaindermediately resume their travel over track 2 as soon as the carrierleaving track 3 has been entered upon track 2 and its grip.

The usual grip opening cam 55 is provided and the carriers are deliveredto track 6 in a known manner, descending this track until they come torest in the relatively small. radius loop 57. The novelty inthispreferred receiving track, per 86, principally resides in the provisionof oblique cuts 58 in therespective rails thereof, at substantially theentrance to the loop 57,which per mits of the ready withdrawal of lugs28' of a given carrier therethrough while leaving no opening, such as at27, through whicha slight cant given to the carrier bythe hand while ifseveral: carriers have accumulated in this receiving track, the

one in the loop grasped by the hand is re-x moved while the othersthereabove are lifted slightly so that but one carrier need-beremoved'at atime.

Referring now tothe modification shown in Fig. 5. Hereinthe carriertraversing track 2 has the right ofway over carriers being despatchedfrom the station shown.

The parts not otherwise particularly noted are:su bstantia1ly the sameas in the previ "ou'sly-described form of device and hence need not.again be referred to. The essential dlfierence betweenthe twoconstructions resides in' the substitution of a lever 60 pivoted *at 61to bracket 10 and having a connection '62 with the latch 32, in place ofthelink 46 and its associated parts. The connection at 62 is preferablya slotted one, to

' permit of free movement between the connected elements, and itoperates in the following manner: Assuming that a carrier 28 I is justbeing despat'ched when a carrier on the main track 2 approaches thestation, as indicated by the dotted-outlined carrier shown to the righton said track,- in Fig. 5;

The clockwise movement of the. latch as bridge i l-is opened swings theinnerje'nd of 'lever 605downward'and its outer end up- "wardasfalsoindicated'by dotted lines in said figurefThis disposition'ofthetreadlei V like free end of lever 60, however, places it' in the pathof the, approaching carrier and if it has not re-descended before thiscarrier encounters it, itwill be positively depressed by the engagementofsaid approaching carrier therewith, which will rock the leverclockwise and the latch counterclockwise,"

releasing the bridge, when spring 43 immedlately closes the ,same,atthe. same t me lifting pulley 21 out of engagement with cable 5, sothat the: pusher 25 descends prematurely and with it the carrier beingdespatched,-unless the latter has already succeedediin so nearlyentering track 2' that its momentum carries itout completely thereinto;in which case its grip will engage cable5 and both carriers will travelon thereafter one closely'behindthe other.

cord, as they reach substantially their lower'most positions in track3,,to effect a re-' engagement of the pulley 21 with cable 5 and are-latching of the bridge in itsupposition. In such case the action isas follows: The carrier being despatched has, let

us say, reached bracketl-3, when the carrier on track2 trips the latchand the bridge closes, this latter carrier immediately passingthereover'. By the time that the through I or main line carrier hascleared the bridge,

have nearly reached the positions inwhich however," the'pusher and thecarrier supported thereby-i'will have dropped until they they are-shownin Fig. 1. 'lhereafter they will continue to descend under-.moinentumand by gravity 'until the bridge is; again raisedand latched andthepusher again;

drawn up. Thistime, if there be no imme diately succeeding carrier ontrack 2' (which 1 seldom happens) vthepusher 25lwill bepulled upsufliciently to "discharge its carrier load onto track 2 in 'thelmannerabovedescribed. In Figs. 6, 7 andfS, I hayeshown still an a j othermodification. -In' this 'constructionf J the carrier being despatchedhas the right of Way, as in the": eiemplification first 'de-'; 7scribed.

Thegrip mechanism comprising jaws 71 and 2 is in fact practicallyarduplicate of that 1 provided upon each of the carriers and-is inrtended to operate in substantially theifsame manner; jaws 71 and'72ofthe carriage corresponding to the carrierjaws 29 and 31 previouslyreferred to." The guides 65, as shown in F 1g. 8, are spaced for thegreater part ofatheir length a'sufficient distance from the cable :5 toprevent the jaws of the" a 1.25

at once apparent. The carrier 28 is inserted M27 and pressed downwardlyagainst the pusher25 which drawscarriage 65 rearwardly andalsocauses ittoapproach the cableuntil its jaws are operativel y engaged with thelatter by a cam 74; which rocks the pivoted jaw T2 up untillit engagescable 5, whereupon both spring Y73 and the cable actto swing it intooperative position; the

cable drawing the carriagealong with it and thereby pulling up thepusher and the carrier supported thereby'until the carrier lifts thebridge l and is ejected onto the'main track 2.
